There are different classification methods according to their chemical properties, production sites, physiological effects, etc.
1) According to the chemical properties of hormones, they are divided into:
Steroid hormones (steroid hormones) such as adrenocortical hormones, sex hormones, etc. Its molecular structure is homologous to cholesterol.
Peptide and protein hormones, such as anterior pituitary hormone and insulin, are composed of amino acids.
Amine hormones, such as epinephrine, norepinephrine, etc., have a small molecular weight and simple structure.
Fatty acid derivatives such as prostaglandins, whose molecular structure is unsaturated fatty acids.
2) According to the hormone-producing organs, it is divided into hypothalamic release hormone, pituitary hormone, adrenocortical hormone, medullary hormone, thyroid hormone, gastrointestinal hormone, renal hormone, etc.
3) According to the effect of hormones, it is divided into prohormone and target glandular hormone.
4) According to the location of the hormone-producing organ, it is divided into positive and ectopic hormones.
5) According to the role of hormones, it is divided into growth and development hormone, substance metabolism hormone, calcium and phosphorus metabolism hormone, water and salt metabolism hormone, life and death hormone, and gastrointestinal hormone.

Hypothalamic hormones: gonadotropin-releasing hormone thyrotropin-releasing hormone Growth hormone-releasing hormone Adrenocorticotropin-releasing hormone.
Pituitary: thyroid-stimulating hormone Gonadotropins Antidiuretic hormone Adrenocorticotropic hormone Growth hormone.
Gonads: Male hormones Estrogen.
Thyroid gland: thyroid hormone.
Pancreatic islets: insulin glucagon.
Excluding plants (plants are not called hormones, but 、、、 hormones such as auxin) are probably that's all.
-
There are two main categories of internal and external hormones.
-
It can be broadly divided into four categories. 1. Steroids, such as adrenocorticotropic hormones and sex hormones. 2. Amino acid derivatives, including thyroxine, adrenomedullary hormone, pineal hormone, etc.
3. Peptides and proteins, such as thalamic hormones, pituitary hormones, gastrointestinal hormones, calcitonin, etc. 4. Fatty acid derivatives, such as prostaglandins.

I'm in college now, and I don't know how detailed you are, which hormones, too many hormones to learn, and what estrogen and progesterone you definitely don't want. If you want, write the name of the hormone, and I'll sort it out for you in detail.
-
This is indeed a lot, and it is difficult to sort out for a while!
-
1 Peptides and protein hormones mainly include hypothalamic regulatory peptides, neurohypophysitary hormones, adenohypophysis hormones, insulin, parathyroid hormone, calcitonin and gastrointestinal hormones.
2 Amine hormones include epinephrine, norepinephrine, and thyroid hormones.
-
1. Proteins and peptides: such as growth hormone, insulin, thyroid-stimulating hormone 2, amino acid derivatives: thyroid hormone, adrenaline.
3. Steroids: sex hormones.
4. Fatty acid derivatives: prostaglandins.

Amino acids, proteins. Remember that it is cholesterol production.

Synthesis of proteins requires certain enzymes, and the composition of ribosomes requires certain structural proteins, so it has proteins; In addition, ribosomal RNA: that is, RRNA, is the most abundant class of RNA, and it is also the largest class of RNA with the largest relative molecular mass among the 3 types of RNA (tRNA, mRNA, RRNA), which combines with proteins to form ribosomes, and its function is to act as a scaffold for mRNA, so that mRNA molecules can be on it, to achieve protein synthesis, for the integrity of the function, he must have RNA.
Dizzy, buy a reference book.
First, the dominant recessive nature of albinism and sickle anemia was determined, and according to the left half of Figure 1, it can be concluded that anemia is a recessive genetic disease, which is bb; Then look at Figure 2, because if it is normal, it can be cut, and if it is not normal, it can't, so B is normal, C is albino, and both are homozygous, only A is heterozygous (because A can cut out three pieces: DNA is a double helix structure, only one of A can be cut, B can be cut all of them, cut into two short and two long, C is not cut) Because albinism is a recessive genetic disease, it is AA, so it can be known that B is AA and C is AA >>>More
p17, the enzyme that catalyzes the hydrolysis of lipase.
Lipase"It is an enzyme, and the enzyme is a protein, so it is natural to use protease. >>>More
