1.

Tyrosine

A non-essential amino acid. In animals it is synthesized from PHENYLALANINE. It is also the precursor of EPINEPHRINE; THYROID HORMONES; and melanin. [from MeSH]

MedGen UID:
21746
Concept ID:
C0041485
Amino Acid, Peptide, or Protein; Biologically Active Substance; Pharmacologic Substance
2.

Angiotensin II

An octapeptide that is a potent but labile vasoconstrictor. It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS. [from MeSH]

MedGen UID:
1932
Concept ID:
C0003009
Amino Acid, Peptide, or Protein; Biologically Active Substance; Pharmacologic Substance
3.

Mitogen

A soluble substance, usually a protein, that induces mitosis in resting cells, thereby causing cell proliferation. [from NCI]

MedGen UID:
7665
Concept ID:
C0026249
Pharmacologic Substance
4.

Angiotensin

Expressed in liver by human AGT Gene (Serpin Family), secreted 485-aa 53-kDa Angiotensinogen is cleaved by renin (in response to lowered blood pressure) to inactive decapeptide Angiotensin I, which is cleaved by ACE to generate active octapeptide vasopressor Angiotensin II (maintains blood pressure and regulates the volume and mineral balance of body fluids). Angiotensin II is cleaved to Angiotensin III heptapeptide, an aldosterone stimulant. [from NCI]

MedGen UID:
1548
Concept ID:
C0003018
Amino Acid, Peptide, or Protein; Biologically Active Substance; Pharmacologic Substance
5.

Mediator of inflammation

The endogenous compounds that mediate inflammation (AUTACOIDS) and related exogenous compounds including the synthetic prostaglandins (PROSTAGLANDINS, SYNTHETIC). [from MeSH]

MedGen UID:
66209
Concept ID:
C0243042
Pharmacologic Substance
6.

Enzyme activation

Conversion of an inactive form of an enzyme to one possessing metabolic activity. It includes 1, activation by ions (activators); 2, activation by cofactors (coenzymes); and 3, conversion of an enzyme precursor (proenzyme or zymogen) to an active enzyme. [from MeSH]

MedGen UID:
41819
Concept ID:
C0014429
Molecular Function
7.

Phosphorylation

The creation of a phosphate derivative of an organic molecule. This is usually achieved by transferring a phosphate group from ATP via the action of a kinase. [from NCI]

MedGen UID:
10742
Concept ID:
C0031715
Molecular Function
8.

Hormones, Hormone Substitutes, and Hormone Antagonists

A collective grouping for both naturally occurring and synthetic hormones, substitutes, and antagonists. [from MeSH]

MedGen UID:
6887
Concept ID:
C0019934
Pharmacologic Substance
