it is an organ. the main organ in the body. I wish your question was a little more clear, like multiple choice would be very helpful to what my choices are.
Answer:
The solubility of any substance in water depends on its polarity. The polar molecule dissolves more easily in the water than the non polar molecule. Amino acids have different polarity at different pH.
(a) (Lys-Ala)3 : The (Lys-Ala)3 contain more positive charge and highly polar the at pH 7 as compared with the (Gly)20 that remains uncharged and has less polarity.
(b) (Glu)20 :This amino acids negatively charged at pH 7 and highly polar than the (Phe-Met)3 which is non polar or less polar and hence least soluble in water.
(c) (Asn-Ser-His)5 is highly polar at pH 3 as compared with the (Ala-Asp-Gly)5 that contains the carboxylate groups of Asp residues that are partially neutral. The (Asn-Ser-His)5 contains = the imidazole groups of His residues are fully polar and soluble in water.
(d) (Asn-Ser-His)5 is polar at pH 6.0 because both have polar side chains Ser but (Asn-Ser-His)5 is only partially partially protonated due to the His side chains. Thus, (Asn-Ser-His)5 is more soluble in water.
Hypersecretion of the population from the anterior pituitary gland causes the condition of galactorrhea.
Prolactin is another name is called luteotropin and its main function is to enable mammals mostly female to produce milk. The pituitary gland secretes it in response to mating, estrogen treatment, ovulation, nursing and eating.
The pituitary gland is attached to the hypothalamus by a short stalk. The pituitary gland has two major parts.
(i) An anterior lobe
(ii) Posterior lobe.
The pituitary gland is controlled by hormones and neurons that comes in the hypothalamus where it acts as a link between brain and endocrine system, and hypothalamus is the endocrine gland itself. Hypothalamus has neurons which regulate secretion of anterior lobe hormones by secreting inhibit and releasing hormones. Every hormone produced by anterior lobe has a releasing hormone.
Prolactin and growth hormones have inhibiting hormone. Releasing hormone helps in stimulating production and it releases hormones from the anterior lobe.
Lysosomes are the vesicles that contain a cell's digestive enzymes. Lysosomes are the vesicles that contain a cell's digestive enzymes.
