According to these studies, a protein intake around 30% of calories may be optimal for weight loss. This amounts to 150 grams per day for someone on a 2000 calorie diet. You can calculate it by multiplying your calorie intake by 0.075.
When we look at hormones that have other endocrine glands as their target we call them tropic hormones. The four tropic hormones of the anterior pituitary gland are: follicle-stimulating hormone (FSH), luteinizing hormone (LH), adrenocorticotropic hormone (ACTH), and thyroid-stimulating hormone (TSH).
Luteinizing hormone (LH) is a glycoprotein hormone consisting of 2 noncovalently bound subunits (alpha and beta). The alpha subunit of LH, follicle-stimulating hormone (FSH), thyroid stimulating hormone (TSH), and human chorionic gonadotropin (hCG) are identical and contain 92 amino acids. The beta subunits of these hormones vary and confer the hormones' specificity.
